Songfacts: "Rain" by the Beatles

The song "Rain," by the Beatles was released in 1966 as the 'B side' for the blockbuster single "Paperback Writer" ("Rain" peaked at #23 on the Billboard charts, while "Paperback Writer" hit #1).
The inspiration for the song was to describe the band's arrival in Australia, which was marked by poor weather and rain. In fact, John Lennon commented that he had "never seen rain as hard as that, except in Tahiti." He also explained that the song was about "people moaning about the weather all the time." "Rain" is one of the Beatles' most critically-acclaimed songs. In fact, the British rock group Oasis liked this song so much they originally named their band The Rain.
